I'm looking for a good how-to on construction and for a burst disk application.

The burst disk will be used in a pneumatic launcher.

This is the TV I have in my media room, MITSUBISHI WD-73840

It is awsome!!!

Yes it has a bulb in the back that has to be replaced, I can get the bulbs for under $100 and they last about 5yrs. No LED fade.

That's the second time in as many days that I have had a rule infraction.

I'm really working on getting in trouble and only myself to blame.

I haven't fully tested the thunderpipe, yet. I have done some tests with water in my yard and it seems to work fine. I'm looking for a wide open spot to test it with a "diffrent' liquid, maybe milk, later this fall when it's a little cooler and more wet from rain.

I understand the mechanics of a piston valve, I'm still trying to learn about qev's.

I've been away from launchers for a few years and you all are way ahead of what I am doing with launchers. I am WAY behind the learning curve

@CooperJS. I think we both messed up you for the post and me for my first reply.

The gold/black thing is a road side pump, the black and red thing behind it is a simple tire pump. the other thing with the sprinkler valve is the copy of the thunderpipe.

I have thought about trying a different valve system, I need to do more research on here and educate myself some more.

Ok I went back and took out any reference to engaging an animal just so I don't get in trouble with the admin

@Demon. All true but only in a survival need, not for fun or to be cruel.

Sorry if my reply to this post offends anyone.

Just a couple of launchers, barrels and a copy of the ThunderpipeFX

I had one of these.

Not very accurate, but if that's all I had and I needed to hold off a charging watermelon or a rabid herd of zucchini squash it would be welcome tool.

Chamber, ball valve, barrel, done

Go to the pneumatic show case and look around it should give you plenty of ideas.

Read what Technician1002 said below my post

My wife works on the railgun project at Dahlgren and up until a month ago I worked at Dahlgren myself. I can tell you they do not "boost" the projectile from a static start the projectile accelerates to mach7 at max power. As for noise, that thing ROCKS!!! If you want to see lots of cool videos go t...

If you have a chamber 4"x16" the volume is 200.9

I add air until the psi is 100psi.

If I add 4" to the chamber but don't add air what would the psi be?

The volume of the new chamber is now 251.2.
